Simulation of objects falling one after another
So if you want to test physics, here what you could try:


Create 3 objects, a cube, a funnel, a plane.





Make your funnel and plane Rigid Bodies, Type > Passive (they are obstacles), Shape > Mesh (the topology will be taken into account).





Make the cube a Rigid Body, Type > Active (it will fall), Shape > Mesh (not necessary in that case I guess). Duplicate the cube. If all your cubes are ready and different, just give the Rigid Body to one of them, select all, then the one with Rigid Body and in 2.8, Object > Rigid Body > Copy From Active (in 2.7, T panel > Physics > Copy From Active).





Start the animation, the cubes fall.





If you want to keep them close to each others, create a Force Field > Force with a negative Strength.
